Affected: PyPI: aiohttp

### Summary

Host-only cookies that are saved with ``CookieJar.save()`` and then restored later with ``CookieJar.load()`` lose their host-only status.

### Impact

Host-only cookies that have been loaded from disk may get sent to subdomains that previously should have been disallowed.
